Type material. Holotype: ♁ (MHBU-ARA-00025217), CHINA: Yunnan Province, Kunming City, Xishan Forest Park (WƜAIJȑȁ), 24.952489°– 24.951981°N, 102.637807°– 102.639223°E, 2200–2300 m a.s.l., 28 May 2022, leg. W. Wang. GoogleMaps Paratypes: 1♁ 1♀ (MHBU-ARA-00025218), same data as holotype GoogleMaps .

Etymology. The specific epithet derives from the ancient literary name of Mt. Xishan, the type locality of the new species. Noun in apposition.

Diagnosis. Males resemble Euochin mii Wang & Li, 2022 in the palp, but can be distinguished by the highly developed flange of embolus, which is undeveloped in E. mii ( Figs 80–82 View FIGURES 80–84 , 85 View FIGURES 85–88 ; see Wang & Li 2022: fig. 5). The female epigyne resembles that of E. nanjiabawa sp. nov. and E. tianhe sp. nov., but the three species can be distinguished by: (1) the shapes of the epigynal windows (wider than long in E. nanjiabawa sp. nov. and E. tianhe sp. nov., while longer than wide in E. lingyi sp. nov.); (2) the distances between the copulatory openings (close to each other in E. lingyi sp. nov. and E. tianhe sp. nov., while far away in E. nanjiabawa sp. nov.); (3) the trajectories of the copulatory ducts (running antero-laterally from the spermatheca in E. nanjiabawa sp. nov. and E. tianhe sp. nov., while running posteriorly in E. lingyi sp. nov.); (4) the sizes of the fertilization ducts (much larger in E. nanjiabawa sp. nov. and E. tianhe sp. nov., while smaller in E. lingyi sp. nov.) (cf. Figs 83–84 View FIGURES 80–84 , 87–88 View FIGURES 85–88 , 115–116, 119–120, 164–165, 168–169).

Description. Male. Habitus see Figs 71–72 View FIGURES 71–74 , 75, 77 View FIGURES 75–79 . Carapace length 2.016; abdomen length 1.847. Eye measurements: AME 0.400, ALE 0.256, PME 0.080, PLE 2.228. Leg measurements: I 4.322 (1.346, 0.660, 1.091, 0.765, 0.460), II 3.107 (1.023, 0.507, 0.627, 0.553, 0.397), III 3.409 (1.141, 0.379, 0.731, 0.786, 0.372), IV 4.083 (1.255, 0.452, 0.87, 0.975, 0.531); leg formula: 1432. Color in ethanol: carapace dark, with white setae forming several longitudinal bands. Dorsal abdomen dark brown, with yellowish-white bands and spots. Chelicera ( Fig. 79 View FIGURES 75–79 ) with two promarginal and one retromarginal teeth. Palp ( Figs 80–82 View FIGURES 80–84 , 85–86 View FIGURES 85–88 ): distal femur and patella covered with long white setae; embolic disc subovate, centrally concaved; embolus with ridge medially and developed flange ventrally; cymbial flange notably extended; RTA tapered, relatively wide.

Female. Habitus see Figs 73–74 View FIGURES 71–74 , 76, 78 View FIGURES 75–79 . Carapace length 1.770; abdomen length 2.513. Eye measurements: AME 0.364, ALE 0.215, PME 0.060, PLE 0.182. Leg measurements: I 2.855 (0.878, 0.437, 0.700, 0.460, 0.380), II 2.503 (0.812, 0.400, 0.517, 0.385, 0.389), III 3.208 (1.022, 0.422, 0.623, 0.694, 0.447), IV 3.725 (1.139, 0.413, 0.806, 0.842, 0.525); leg formula: 4312. Color in ethanol: body like that of male, but lighter in coloration. Chelicera as in male. Epigyne ( Figs 83–84 View FIGURES 80–84 , 87–88 View FIGURES 85–88 ): epigynal window large, elongated longitudinally, with narrow median septum; copulatory opening at posterior margin of epigynal window; copulatory duct connected with central inner part of spermatheca, stretching posteriorly to copulatory opening; spermatheca circular, with top joining fertilization duct.
